Yesterday I had sex with an escort, which lasted about 15-25 minutes maybe less. The escort applied what seemed like lubricant directly to my penis, I didnt have a condom at the moment. Later she began to give me oral, this time with a condom. After this we had vaginal sex, with a condom on still. This lasted for a few minutes before I came and decided to get a new condom. The same cycle repeated, this time lasting a little longer. So my question is, am I at risk of getting any STD? I was protected the whole time.
